When you're dealing with GLP-1/GIP receptor interaction studies, finding consistent matrial batch-to-batch is actually the bigger headache than where to source it — we've had labs come back after running bad copies with purity swings of 2-3%. We hold it at ≥99.5% by HPLC, and what that means for your is you're not chasing impurities that could throw off basal readings, especially in chronic dosing protocols that run 4-6 weeks.
It's a in 500mg or 1000mg per vial, usually 10 vials to a box, but our company can do smaller runs if you're just validating a new assay (20 vials or so) or step up to bulk kilos once you've locked in your model. Most buyers go with the 1000mg vials for efficieny but the 500mg is easier if you're reconstituting for multiple endpoint assays — less waste per thaw.
MOQ is 1 box for first orders, but honestly sustainability hinges on storage; we recommend -20°C steady, not just cool dry place, because the peptide chain — C225H348N48O68 is pretty massive at about 4813.5 g/mol — begins flexing above -5°C and you'll see shorter bioactivity windows within 3-4 months if frozen improperly.
For chronic metabolic studies where obesity or diabetes models require clean weekly dosing, the 24-month shelf life is fine if you've kept it at temperture, but this isn't ideal for acute IV pharmacokinetics because the lyophilization process can leave minor moisture that clusters in solution — we usually have stock on hand so lead time is roughly 10-15 working days, but confirm before ordering for large bulk.
Nothing worse than running half your cohort and realizing the second vial batch has shifted potency — we supply full COAs from our GMP facility, tested at 99.5% minimum with residual solvents below 1 ppm, so you're covered across multiple shipments without the spec-sheet roulette form middlemen who can't even tell you teh chromatography column type.
We can start with as little as a single box, which is 10 vials. For bulk orders, we offer volume discounts—just let us know how much you need.
Yes, we provide a COA with every batch. It shows the actual purity, identity, and other specs. Just request it when you place your order.
If we have stock, it ships within 1-3 business days. For custom packaging or larger bulk orders, add about 5-7 business days for production.
Keep it in a cool, dry place. We recommend storing at -20°C for maximum stability. The shelf life is 24 months if stored properly.
Absolutely. We can customize vial sizes and box quantities for bulk orders. Just specify your requirements, and we'll work out the details.
